Patented Dec. 6, 1932 UNITED STATES PATENT OFFICE HENRY RICHIVIOND, 0F FBENCHWOOD, PRESTON, ENGLAND Application filed. March 14, 1931, SeriaI No. 522,722,

This invention relates to weavers shuttles of the kind in which a weft-pirn is carried in a detachable manner on a peg or skewer within the shuttle which is provided at one or both ends with a metallic nose or tip. The invention has for its object to provide an improved and simplified construction whereby the weft-carrying capacity of such shuttles will be increased.

To this end and according to the present invention the peg which carries the pirn within the shuttle is fixedly mounted on the shuttle, and means are provided for retaining or locking the pirn on the peg, such for example as one or more spring clips carried by the shuttle, and adapted to engage the end portion of the pirn so as to hold this on the peg; means are preferably embodied for locking or maintaining these parts in engagement.

The peg may be formed integral with the shuttle heel tip and conveniently means are also provided for fixing the peg and tip in position after insertion and to this end the portion of the peg which lies adjacent to the tip and passes through the nose of the shuttle may be tapered to engage closely a correspondingly tapered hole in the nose of the shuttle so that when the peg is driven into the nose it is securely wedged in position.

The pirn may have its end formed with a multilated annular flange and an annular recess behind this flange, members carried by the shuttle and formed for example either integral with the shuttle or as separate spring members mounted thereon being adapted to engage the annular recess and multilated flange. For the purpose of maintaining engagement between these members and the end of the pirn locking means may be provided, for example an automatically locking device in the form of a spring actuated plate carried on the peg and constructed and arranged so as to maintain the said parts in engagement.

Three constructions according to the invention are illustrated somewhat diagrammatically and by way of example in the accompanying drawing, in which Figure 1 is a plan of one construction,

Figure 2 is a section on the line 2-2 of Figure 1 on an enlarged scale,

Figures 8 and 4 are views similar to Figures 1 and 2 respectively but illustrating another construction, and

Figures 5 and 6 show similar views of yet a further construction.

In the construction illustrated in Figures 1 and 2 the shuttle body A has metallic tips B one of which is provided with an integral elongated tang B passing through the nose of the shuttle and projecting into the shuttle recess A so as to serve as a peg for the pirn C. The tang or pirn-peg B is tapered as shown, at that part which is adjacent to the tip and passes through the nose of the shuttle, this tapered part enabling the peg to be firmly wedged in the nose of the shuttle. In this construction the peg B is also screwthreaded at B to receive a lock-nut B which, together with washers B serves not only as additional means for locking the peg to the shuttle body, but at the same time secures in position in the shuttle spring clips D adapted to engage an annular recess C formed behind ,a flange C on the end of the pirn C. The lock-nut B may be itself prevented from working loose by a pin B carried by the shuttle body and bearing on one of the flats of the nut.

The pirn C can be readily removed by flexing one or both of the clips D outwards whereupon the pirn can be withdrawn.

The alternative construction illustrated in Figures 3 and L is generally similar to that above described except that, instead of a locknut, a spring F is arranged to bear at one end on a retaining plate F and at the other end on the washers 13* which serve to lock spring clips D to the shuttle body. The pirn G has its end formed with an annular flange C mutilated to form flats C, an annular groove or recess C being provided behind this flange. The retaining plate F is longitudinally movable on the peg and has lateral projections F adapted to engage the mutilated portions or flats C the flange C clips D andplate F thus together forming a bayonet joint, The pirn can be removed-by forcing the plate F- along the peg against the action of the spring F whereupon rotation of the pirn through permits the flange C to pass between the clips D A modified construction is illustrated in Figures 5 and 6 in'which, instead of the spring clips as above described, abutments G are provided on the interior of the shuttle adapted normally to engage behind the flange C A spring-pressed retaining plate H is formed with a laterally projecting portion H (Figure 6) to engage one of the flats G on the pirn in a similar manner to that above described. This construction is advantageous in that spring clips or the like can be dis-e l the usual skewer and shuttle tongue are employed. Thus a longer pirn can be employed enabling the loom to run for a longer period at a time without stopping for replenishing the shuttle. I

What I claim as my invention and desire to secure by Letters Patent is 1. A weavers shuttle for pirns and rewound wefts comprising in combination a shnttle body, a shuttle peg fixedly mounted on said shuttle body, a retaining device carried by the shuttle for engaging the pirn to retain it on the peg and locking means for maintaining said retaining device and the pirn in engagement with each other. i

2. A weavers shuttle for pirns and 'rewound wefts comprising in combination a shuttle body, a shuttle peg fixedly mounted on said shuttle body, and a pair of resilient clips adapted to engage on opposite sides of a pirn toretain the same inposition on the shuttle peg. 3. A weavers shuttle for pirns and rewound wefts comprising in combination a shuttle body having an abutment thereon adapted to engage a pirn, a shuttle peg fixedly mounted on saidshuttle bodyand locking means for retaining the pirn in a position of engagement with said abutment.
